Both concepts are related but separate. I'd argue that monitoring is the act of alerting or taking action when some metric is out of bounds with normal values.

Both concepts are related but separate. I'd argue that monitoring is the act of alerting or taking action when some metric is out of bounds with normal values. Those values are based on absolute thresholds, or some changing thresholds based on historical values. Observability is the ability to see what's happening across and between multiple systems so that any issues raised by monitoring can be diagnosed quickly. "I know theres a problem vs I know which part of the system its happening in"
- ittan 5y agoNot to be rude, Monitoring is observing problems and then responding to the alarm in realtime. You cannot compare the two. Yet we do in certain circumstances and that is a loss in understanding, which I am sad about.
- mmanciop 5y agoI very much agree: observability is a property of a system, like transparency is for glass. Monitoring is what you need to do with a lot of systems to make them observable.
